Fusion of Ubiquitin to HIV Gag Impairs Human Monocyte-Derived Dendritic Cell Maturation and Reduces Ability to Induce Gag T Cell Responses

Figure 8

Expression of PDL1 and production of IL-10 by transduced moDCs.

MoDCs were transduced with either the non-ubiquitinated (0x, hatched bar or closed circle) or ubiquitinated (1x, grey bar or closed square) HIV-1 CN54 gag constructs or untransduced (control, open bar). Following an overnight incubation, DCs were then matured with LPS and IFNγ for a further 24 hrs. Cells and supernatants were harvested and A) cells were stained with anti-PDL1 and analysed by flow cytometry and B) the production of IL-10 was determined by ELISA. Graph A) represents the mean±SD of 5 donors and graph B) represents 6 individual donors.
